U.S. Census Bureau Announces 2010 Census Population Counts -- Apportionment Counts Delivered to President
"The U.S. Census Bureau announced today that the 2010 Census showed the resident population of the United States on April 1, 2010, was 308,745,538.

The resident population represented an increase of 9.7 percent over the 2000 U.S. resident population of 281,421,906. Commerce Secretary Gary Locke, Acting Commerce Deputy Secretary Rebecca Blank and Census Bureau Director Robert Groves unveiled the official counts at the National Press Club in Washington, D.C.

"A big thanks to the American public for its overwhelming response to the 2010 Census," U.S. Commerce Secretary Gary Locke said. "The result was a successful count that came in on time and well under budget, with a final 2010 Census savings of $1.87 billion."

Rebecca Blank, now Acting Deputy Secretary of Commerce who has overseen the 2010 Census as Under Secretary for Economic Affairs, echoed Locke. "The 2010 Census was a massive undertaking, and in reporting these first results, we renew our commitment to our great American democracy peacefully, fairly and openly for the 23rd time in our nation's history."

The U.S. resident population represents the total number of people in the 50 states and the District of Columbia.

The most populous state was California (37,253,956); the least populous, Wyoming (563,626). The state that gained the most numerically since the 2000 Census was Texas (up 4,293,741 to 25,145,561) and the state that gained the most as a percentage of its 2000 Census count was Nevada (up 35.1% to 2,700,551).

Regionally, the South and the West picked up the bulk of the population increase, 14,318,924 and 8,747,621, respectively. But the Northeast and the Midwest also grew: 1,722,862 and 2,534,225.

Additionally, Puerto Rico's resident population was 3,725,789, a 2.2 percent decrease over the number counted a decade earlier..."
